Description

Field of the invention

This invention relates to process for allowing a real-time economic transaction between two parties connected through a computer network, one of the parties being an individual or a company paying a given amount of money either for a service received or goods purchased through the network or for an another reason and the other party being an individual or a company collecting the said amount. The invention also relates to a system for implementing the said process.

For a simplest wording of this specification, thereafter the paying party shall be the "payer" and the collecting party, the "payee".

Background of the invention

Each time there is more and more cost-associated supply and demand of services and goods through computer networks such as for instance, Internet. This means that, through a computer network of this kind and by means of related suitable computer equipments, a purchaser can connect an offerer and receive a service or purchase a product selected and immediately pay it or agree the payment by means of the payer transmitting the data related to a banking account or an electronic card associated to the payer's banking account, so that the payee can manage the collection of the amount agreed upon by directly having access to the payer's banking account.

With this procedure presently used, the payer sustains a great risk because on one hand he is left to the mercy of the payee's higher or lower level of honesty, which is acquainted with a tag of his banking account, and on the other hand, he is exposed to the risk that when he is being transmitting the said data associated to a banking account through a free access computer network, an unscrupulous individual can capture the said data and fraudulently use them to his/her own profit.

The process of the invention implies the use of "card money", that is to say amounts of money associated to a computer protocol which may be authenticated, stored, managed and transmitted by computer equipments. A typical application of the use of card money is that of cards provided with integrated circuit (referred thereafter as IC cards), popularized with the name of "smart cards". The said cards are well-known and consist in a physical support having standard dimensions on which contact terminals are arranged which can contact related terminals of reading-recording equipments through which a small microchip or data processing microunit (CPU) built in the said support and input and output digital data are transmitted between this later and outside. The said CPU supports a program for authenticating and managing digital data referring to card money and it has available a programmable memory , for example an EEPROM, for their temporary storage. With the said arrangement, an user of the said IC card can load, through a suitable reading-recording device a given amount of card money from an external temporary memory unit, for example from a banking account, to the IC card temporary memory unit and vice versa, that is to say, to unload a selected amount of money from the said card memory unit to an external memory unit, for example, a banking account or collecting terminal at any business or service company. Therefore, it is possible to load and unload given amounts of money to/from the said card and it is typically used for collecting and paying small every day small monetary transactions involved in modern life.

The document GB 2 308 001 discloses a IC card reading-recording apparatus and a process for operating with an IC card by interacting with another information system. The said process contemplates the possibility of connecting the said reading-recording apparatus to a personal computer for carrying out an economic transaction between the user's IC card and another IC card communicated through a telephone line.

The operative process proposed by this patent always demands the use of a IC card reading-recording device by at least the payer and in the event there exists a money transfer between two parties, that means that the said payer must introduce data related to a payee's IC card, which can be managed by another reading-recording device or by the same, in which case it will have available a second slot for inserting IC cards.

The document WO 92/21110 discloses a system for having access to an individual or an company rendering services through a telephone equipment. Also in this case, an authenticating device is used, such as for example an IC card, for transmitting identifying and/or confidential data from the calling party to the other party rendering the service. In some cases, such as for example for renting goods, in addition to the authenticating device it is foreseen to load the IC card with a preestablished amount of payment, monetary or equivalent units which are successively discounted as related goods are rented.

In both cases it is obvious that there exists between the two parties a transmission of identifying and/or confidential data with above risks that involves.

The patent WO 99/03073 of this applicant discloses a portable device for carrying out remote money transactions using an IC card. The said device has an IC card reading-recording device built-in, a standard safety module, a modem and a cable adapted for connecting to the telephone line through a standard connector. This device is useful, for example, for establishing communication through a telephone line with a banking account and proceeding to remotely loading-unloading amounts of card money to or from the IC card.

On the other hand, also telephone devices are known which have a built-in computer, including an alphanumeric keyboard and a tactile screen for access to Internet and videoconferences.

WO 97/19414 A1 discloses a computer network payment system in which monetary funds can be created and used for payment. When creating the funds, a unique serial number or cash key is generated and stored in a computer of a central electronic bank remote from the user's computer. When using the funds for payment, a new cash key is generated and again stored in the computer of the electronic bank. The new cash key represents the balance of the user's funds after the payment is deducted.

EP 0 778 551 A2 discloses an electronic currency system in which electronic money can be transferred between IC cards. This document further discloses a variety of terminals for use with IC cards of the system.

Although the systems disclosed in mentioned patents make possible remote interconnection between two parties for exchanging information, including transactions of card money with IC card support, they do not fully deal with the problems of real-time paying-collecting services received-rendered or goods purchased-sold through Internet without the need of transmission confidential data through the network is required and without one of the parties having access to the banking account or to the other party's authenticating device.

Short exposure of the invention

Therefore, an object of this invention is to provide a process for allowing an economic transaction between a payer and a payee connected through a computer network, by means of which the payer can release, in real time, a given amount of money to the payee and the payee can receive the said given amount at once without at any moment there exists on the side of the payer any transmission at all of data associated to a banking account thereof and, thus, without the payee has at any moment access to the said banking account and, in general, without the identification of the payer by the payee be required, preventing thus, in addition, the possibility that the said data come into the hands of a third party.

To achieve this object, this invention provides a process and a system having the features of

claims

1 and 10, respectively.

According to the process of the present invention, the payer first connects the payee through the network for receiving a service or purchasing goods and thereafter he loads an amount of money from his banking account, preferably through a second telecommunication line, while keeping the said first connection with the payee open. When the payer received the information referring to the amount agreed to be paid through the said second line, he preferably proceeds to load exactly the said amount from his banking account through the said second line to the payer's temporary memory means, and thereafter he preferably proceeds to send an order which will generate the transmission of the said amount from the said temporary memory means to the payee's collecting equipment. With this modality, although the payer carries out two connections and keeps them simultaneously open, one with the banking account and the other with the payer, respectively, at no moment the payee has access to the payer's account, but only to the amount loaded in the payer's temporary memory means allowed by him.

The system of the invention foresees the existence of different equipments for implementing the different modalities of the process. For example, the payer has available:

means based on a computer capable to be connected to the said computer network to have access to the payee's computer equipments by means of a standard communication program and in addition he has available, the payer's temporary memory unit, a reading-recording device of the said temporary memory unit and a standard safety module, associated to the said payer's computer.

Means, for instance a second modem are in addition associated to the payer's equipments for carrying out the said connection through a second telecommunication line or sharing a same line.

The said reading-recording device of the payer's temporary memory unit, the said standard safety module and, optionally, the said second modem, can either be built up in the payer's computer or form part of an external reading-recording unit, communicated with the said payer's computer through a connecting cable by means of a suitable communication protocol, for example, a RS232. Also, the said payer's temporary memory unit can be built in the payer's computer or it can be withdrawable and packtype, in which case the said temporary memory unit is typically comprised in a standard IC card and the said reading-recording device is a standard IC card reading-recording device, incorporating or not a modem.

As IC cards reading-recording external unit with built-in modem the portable device disclosed in the patent of this applicant, WO 99/03073 provided with a connecting cable with the computer added is useful.

The operating modalities designed to the payee are as follows. According to a first modality, the payee proceeds to load in his own temporary memory means the amount of money received from the payer to his own temporary memory means at same time that the said amount is received. According to a second modality, the payee connects the banking account he holds for transferring the amount received, which is temporarily loaded in the temporary memory means, to the said banking account once the connection with the payer is finished or to carry out the said transfer during a connection carried out through a second telecommunication line, keeping the first connection with the payer open. In this second case, even the payee's temporary memory means could be omitted directly loading the incoming amount to the payee's banking account.

As in the case of the payer, for the payee the system of this invention foresees computer-based means, temporary memory means and the said temporary memory reading-recording device, as well as a standard safety module. The said reading-recording device of the payee's temporary memory unit, the said standard safety module and optionally the said second modem can either be built in the payee's computer or form part of an external reading-recording unit, communicated with the said payee's computer through a connecting cable by means of a suitable communication protocol, for example, a RS232. Also, the said payee's temporary memory unit can be built in the payee's computer or it can be withdrawable and packtype, in which case the said temporary memory unit typically consists in a standard IC card and the said reading-recording device is a standard IC card reading-recording device. Also, for the payee the portable device disclosed in the patent WO 99/03073 of this applicant provided with a suitable connecting cable to the computer would be useful.

A detailed of the invention is given below with reference to the appended drawings, in which:

Fig. 1 is an illustrative diagram of an example which shows, when combined with one of the embodiments of Fig. 3 or Fig. 4 with respect to the mode of operation of the payer, a first modality of the operation as for the payee;

FIG. 2 is an illustrative diagram of another example which shows, when combined with one of the embodiments of Fig. 3 or Fig. 4 with respect to the mode of operation of the payer, said first modality of operation;

Fig. 3 is an illustrative diagram of an example of embodiment according to a second modality of operation, as well for the payer as for the payee; and

Fig. 4 is an illustrative diagram of another example of embodiment according to the said second modality of operation.

Detailed description of the examples of embodiment

Referring first to Fig. 1, a computer 1 of the payer is connected through a computer network by means of a telecommunication line 5 to the payee's computer 2. The payer's IC card reading-recording device 3 is connected by a connecting cable 6 to the payer's computer 1 while the payee's IC cards 60 reading-recording device 4 is connected by means of a connecting cable 7 to the payee's computer 2. As well the payer's computer 1 as the payee's computer 2 have available corresponding standard modem and communication program for interconnecting each other through the computer line, the said conventional equipments being mostly domestic PC.

IC cards

50, 60 are cards which include an integrated circuit comprising a microprocessor, a temporary memory unit for temporarily storing digital data and a program for managing the said data.

IC cards

50, 60 includes, on their surface, terminals which can contact related terminals of the reading-recording devices for transferring data to each other. As well the sizes of the card as the sizes of the terminals located on this later are standardized according to the standard "Smart Card" ISO 7816 (with asynchronous protocol ISO 7816/3) and are generally used throughout the world while the reading-recording devices are adapted to the said standardized sizes.

With the arrangement of Fig. 1, the payer has available an IC card 50 in the temporary memory 10 of which an amount of card money estimated enough for paying a service or goods sought to be ordered through the network is stored. The said amount was previously loaded through any of the conventional procedures well-known by the user of that kind of cards. According to the present invention, however, the amount would be loaded after a connection with the payee has been established and while keeping this connection open. During this connection between the payer and the payee through the said computer line, the payee communicates to the payer an amount to be paid for a service received or to be received or for goods purchased or to be purchased. At that moment, the payer introduces an order which validates through the payer's computer 1, the transfer of the said amount from the payer's IC card 50 temporary memory means 10, by means of the payer's reading-recording device 3, to the payee's computer 2, which in this example, would order the load of the said amount to a related temporary memory 20 of the payee's IC card 60 by means of the payee's reading-recording device 4. After the safe reception of the amount agreed upon, the payee releases the payer an electronic message of agreement through the network, which can include other data of financial or fiscal interest (in which case the payer has to transfer an identity authentication) and be printed by the payer with conventional printing means. At this point, the connection between the payer and the payee can be cancelled. Later on, the payee could transfer the card money from his IC card 50 to a different destination, using any of the said conventional and well-known procedures.

The example illustrated in Fig. 2 allows to operate in a way identical to that of Fig. 1. The difference stands in the fact that in this case, the respective payer's and payee's IC card reading-

recording devices

50, 60 including safety modules are respectively built in the payer's computer 1 and in the payee's computer 2, which in addition will be provided with respective slots for inserting IC card.

Now referring to Fig. 3, as up to now the payer's computer 1 is connected through the computer network by means of the telecommunication line 5 to the payee's computer 2. Also, the payer's IC card 50 reading-recording device 30 is connected by a connecting cable 6 to the payer's computer 1 while the payee's IC card 40 reading-recording device is connected by means of a connecting cable 7 to the payer's computer 2, but in this case, the payer's reading-recording device 30 includes a modem and is connected through a second telecommunication line 8 to the payer's banking account 11 in a finance company 12, and in same way, the payer's reading-recording device 40 includes a modem and is connected through a second telecommunication line 9 to the payer's banking account 21 in a finance company 22. The reading-

recording devices

30, 40 can be as those disclosed in the patent WO 99/03073 but with

related connections

6, 7 to the payer and

payee computers

1, 2, respectively.

The said arrangement, in addition to allow an embodiment identical to the one disclosed as reference in Figs. 1 and 2, allows a new embodiment which is as exposed below. First the communication between the payer and the payee is established in above disclosed conventional way, without the payer having to necessarily dispose of any amount of money loaded in the temporary memory 10 of his IC card 50. At the moment when the payer receives the information relative to the amount he must pay the payee, the payer establishes a second connection through a second line 8 with his banking account 11, keeping the communication with the payee open through the first line 5. Then, the payer orders the transfer of the accurate amount to be paid from his banking account 11 to the temporary memory 10 of his IC card 50. At that moment, the payer may cancel the connection through the second line 8 with his banking account. Thereafter, the payer orders the transfer of the amount stored in memory 10 of his IC card 50 to the payee's computer 2, which can order to load the said incoming amount to related temporary memory 20 of his IC card 60, or even to load it directly to his banking account through a connection by means of related second line 9.

With the example of embodiment illustrated in Fig. 4, same embodiment is allowed as in the example of Fig. 3. The difference stands in the fact that in this case, instead of the

temporary memories

10, 20 and remaining electronic elements of respective payer's and payee's

IC cards

50, 60,

respective computers

1, 2 incorporate related specific temporary memory units built in them and related management programs, as well as related reading-recording devices, safety modules and respective second modems, instead of the respective external reading-

recording devices

30, 40. In this case, no standardized withdrawable portable IC cards or reading-recording devices thereof are used.

In the embodiment illustrated in the examples of embodiment of Fig. 3 and 4, there exists a communication route between the payer's computer 1 and a banking account 11 he holds in a banking institution 12 and/or a communication route between the payer's computer 2 and a banking account 21 he holds in a banking institution 22, but in no case there exists the possibility the payee has an access to the payer's banking account or vice versa, nor transmission of confidential information referring to the said accounts through the network.

In above disclosed embodiments which foresee a simultaneous double connection by means of two modems, the said double connection, instead of being carried out using two telecommunication lines, can be carried out through a same line using a device making them compatible.

A man of the art could introduce multiple variations in above process and system without being beyond the scope of this invention which is defined by appended claims.
